After you cleaned the arrestor, does it have supports on it (yellow markings).
IF so, and you want to remove screen. I would just "punch out" (RED area )
or cut the screen and leave the supports.
Hope it make sense what I am trying to say. Don't cut the support away. Just the screen....
Does the other end of the screen push agains anything for support. Our RTV's didn't have it. We just had a pissy screen on the end of the tailpipe held by one
little screw thingy.....
Like another member stated before. If you plan on running on government land. Just clean.
